A year-round, cold-conditions baselayer that manages moisture during high-output pursuits on foot, skis or two wheels. Basis PeakWool® features a highly breathable, layered construction that blends the benefits of natural and synthetic fibers for premium, buttery soft comfort. The PeakWool® fabric offers soft, ultra-fine merino wool next-to-skin to wick moisture, and a quick-drying polyester outer that adds strength and durability. The classic zip-neck design provides added coverage and quick ventilation, while flatlock seams minimize chafe and ease layering.
